Could you clarify this statement. There are TWO choices You received an answer to 'override' and stop sites from auto-refreshing, but the browser doesn't auto-refresh any Webpage on its own at all. That's the Website's design whether you see a page auto-refresh or not. The blame is on a Webpage if it 'tells' FireFox to auto-refresh, and FF just obeys the 'command' from a Webpage to auto-refresh.
Example: Weather sites with forecasts, Satellite Imagery, and Radar. Anyway, it's nice to know there's a Config setting that override and stop all auto-refreshing, if I would ever need it. The second one is "accessibility. Double-Click on that and it will change to 'true'.
This set of directions is not working for me. I am probably NOT doing something correctly.

Using the method below will allow you to programmatically exclude fields from validation and the object model created by the Angular Reactive Form. This tutorial will follow the example of a component used to enter an address.
If the user selects United States from the country dropdown, the State field is active. If the user selects any other country, the State input field will automatically be disabled. If the user re-selects the United States from the country dropdown, the State field will be enabled once more. Step 2: Declare and initialise the following class variables.
What you initialise countries and states to will depend on your application.
Below is just a simple example. Step 3: Next create a function to initialise the ReactiveForm called addressForm in this example. My preference is to implement the ngOnInit function and then call seperate functions to initialise the form:. In the initialisation of the addressForm I have kept all the default values blank and made all fields required except Address Line 2.
We have now completed the basic set up of our address component. Step 3: Now use the power of Observable s to watch for changes to the form. Essentially, a subscription will be set up to execute a function every time the value of Country is changed.
This is much more efficient than the AngularJS method of using the digest cycle to poll the form. It is also a lot cleaner and less intessive on the browser to use Observable invocations as they only fire when the form changes. In some scenarios you may want to watch the entire form, but in this case we are fine to just subscribe to the Country field.
Once again, I prefer to break up my initialisation logic in to seperate functions. Declare a function to watch the state field called onChanges and then called it from ngOnInit with this. The onChanges function is simple.
It gets the country control within the addressForm and subscribes to any value changes. Whenever the value of the Country field changes, the function is executed. The input to the function is the new value of the Country field. Use an if-statement to check the selected value for the country.
The enable and disable methods are simply wrappers for boolean properties on the FormControl. Step 4: Optional. If you are using Bootstrap 3, you will have default support for disabled input controls.

This is an exciting addition to the Router as it finally gives us the ability to differentiate between an imperative navigation ex, the user clicked a router-link and a location-change navigation ex, the user clicked the Back or Forward buttons in the browser chrome. This insight is something that I struggled with in Angular 5 when building my "restore scroll position" polyfill ; and, is something that will make custom behaviors like my polyfill much easier to implement.
Even navigation events that are considering "going back" or "going forward" within the Browser's history are given a unique ID. What's great about the Router updates in Angular 6 is that the NavigationStart event now also includes the unique ID of the navigation event being restored by a "popstate" event ie, a non-imperative navigation event.
This restored state ID is provided in a property called, "restoredState". And, we can use the existence of this property to determine if the navigation was triggered in attempt to move to a completely new browser state the "restoredState" will be null ; or, if the navigation was triggered in an attempt to move to an historical browser state.
ASIDE : The NavigationStart event also includes a "navigationTrigger" property to provide a more technical indication of what triggered the navigation; at this time, however, I am not yet sure what additional value there is to knowing why the navigation occurred.
I am sure that there are use-cases for its consumption; but, for the time-being, knowing the restored state seems like the most valuable facet of this update. To explore this Router behavior, I created a simple demo in which you can navigate between three routes, each of which has three anchor links. As you navigate through the app, the details of the NavigationStart event are logged to the console. And, if you go "back" and "forward" through your Browser's history, you will see how the IDs of previous navigation events are presented as the "restoredState" IDs:.
As you can see, as we navigate through the application, each NavigationStart event is listed as an "imperative" navigation action that has no "restoredState" property. This is really cool! Obviously, the Angular team added this functionality to enable their own "restore scroll" functionality. However, said functionality only works on the primary viewport as far as I understand. As such, I believe that I can use this functionality to greatly improve the stability of my own "restore scroll" polyfill, which works on an arbitrary collection of scrollable containers.
I am not sure I understand what you are saying. In my experience, when I use the Router to navigate, the History is kept in tact, unless I explicitly tell it to replace the replaceUrl property to overwrite the current history item:. By default, the Router seems to work naturally with the History object.
Hi Ben, I have used same component for tabbed navigation. Tabbed navigation is very much like any other navigation - it only differs in some of the implementation details. Then, in your View components, you can subscribe to the Fragment and use it to change the View ie, render the appropriate Tab.
This way, changing the tab changes the URL, which is stored in the History. This is actually something I've been meaning to try and put a demo together for. I will try to prioritize this. Also, you could take it one step further and even use the Router to render the Tab. So, just like you would render any other View with the Router, you could have something like pseudo-code :.
Of course, that would require that you use the [routerLink] directive in your Tab nav; but, that's easy enough. Hi, as soon as I am pressing back button on landing page, it navigates away to default browser page.
The app exits without hitting router events, router guard, ngDestroy, ionViewWillLeave or window:onbeforeunload event. Please suggest. I have to restrict that navigation without disabling the back button. I have to show a pop up there customized. That is surprising that not even window:onbeforeunload isn't working.GitHub is home to over 50 million developers working together to host and review code, manage projects, and build software together.

How Do I disable the Refresh button of browser
You signed in with another tab or window. Reload to refresh your session. You signed out in another tab or window.When the web application project separated from the front and back platform goes online, some errors will occur due to the automatic caching strategy of the browser. For example, the front and back platforms of the project are upgraded from v1.
At this time, due to the browser cache, the user still uses the v1. This will cause the foreground of v1. This paper takes angular as an example to illustrate a solution of automatic refresh of project browser after foreground update. If you want to implement the function of forcing browser refresh again after foreground update, you need to add a version number to control.
Read the version number of the foreground when the system starts, and then compare it with the version number on the server. If the version number is the same, it means that the version of the foreground currently loaded by the browser is the same as that provided by the server, and nothing is done; if the version number is different, it means that the version currently loaded by the browser is not the same as that provided by the server, then the browser is forced to refresh to clear the impact of the cache.
In the actual production project, it can be established anywhere under the SRC folder as required. To compare the version numbers, you need to obtain two version numbers: the first is the version number of the web application running, and the second is the version number of the web application provided by the server.
When the two version numbers are inconsistent, it means that the current running version is inconsistent with the version provided by the server, and forced refresh should be performed.
It is worth noting that in the background of the request config. In this case, you need to make some articles on the requested header to force the browser to make a request config. This paper uses the method of exposing the version files in the foreground and comparing them to determine whether to force refreshing the browser cache. After working, I try to build […].
